摘　　要：目的探讨B型超声在急性玻璃体后脱离(PVD)的诊断价值。方法应用B型超声诊断技术对434例(434只眼)急性PVD患者进行检查、分析,根据PVD的声像图特点分为完全性和不完全性PVD。结果完全性PVD 289只眼(占66.59%),而不完全性PVD 145只眼(占33.41%),其中有28只眼合并少量玻璃体出血,仔细寻找发现裂孔19只眼,给予裂孔周边视网膜光凝,术后随访6个月无复发。结论 B型超声检查可以准确地诊断急性PVD,在玻璃体视网膜疾病的病程和预后中起重要的作用。Objective To discuss the utility of ultrasound in diagnosis of acute posterior vitreous detachment（PVD）.Methods 434 cases of PVD were reviewed.There are two types： complete PVD and partial PVD based on the ultrasonographic characteristics and diagnosis.Results 289 eyes（66.59%） were diagnosed as complete PVD,and 145 eyes（33.41%） were diagnosed as partial PVD.Among the 28 eyes with a small amount of hemorrhage of vitreous humor,retinal breaks of 19 eyes can be found by careful examination.Given the photocoagulation nicely to heal the breaks,6 months later eyes were kept better.Conclusion Ultrasonography can accurately diagnose acute PVD and plays an important role in the clinical course and prognosis of vitreous humor and retina.
